CALL function to extract data from a structure table

Hi Gurus,
Anyone knows how to write a call function to extract data from a structure table?
Your help is very much appreciated.
Thanks alot.

Hi,
structure doesnot hold any data. instead of it you can check the stucture in which table it is used, find the table name,use select query to extract the data u needed.
you can use where used list option to find the structure in which table it is used.

Hi Rahul,
You can use following tables to extact default material characteristics.
CABN,CABNT,CAWN & CAWNT
And you can also refer following code where I have used FM's -
*&--- Select class type available for material table (MARA)
    SELECT klart
            FROM tcla
            INTO TABLE t_klart
            WHERE obtab = c_mara AND
                  klart = '300'.    " GIves Material class type
REFRESH t_objkeys.
    LOOP AT t_klart INTO w_klart.
      CLEAR : w_objkeys.
      w_objkeys-class_type     = w_klart.
      w_objkeys-objectkey      = w_matnr2.      "material number
      w_objkeys-objecttable    = c_mara.          " MARA
      APPEND w_objkeys TO t_objkeys.
      CLEAR : w_klart,
              w_objkeys.
    ENDLOOP.
REFRESH : t_allocations, t_class_char1, t_class_char.
*&---FM to get the Class Name for the material
    CALL FUNCTION 'CLBPAX_READ_CLASSIFICATIONS'

        t_allocations     = t_allocations
        t_valuations_char = t_value_char
        t_valuations_num = t_value_num.
IF t_allocations[] IS NOT INITIAL.
    LOOP AT t_allocations INTO w_allocations WHERE class_type = '300'.

Extract article from HTML code

Hi,
I'm trying to build a search engine for an RSS feed. Thing is i'm trying to store every article as a BLOB field in the database. To optimize my search i'll need to extract the article only and nothing else (no unrelated hyperlinks or html code)
I'm using the HTMLEditoKit of swing to get the html content without the code, but that's not enough. I need to clean the page of things like headers and footers (they affect the search results)

i already parsed the XML in the RSS...i've got informa ; the problem is the article itself
Take this article for example: [http://news.bbc.co.uk/2/hi/europe/7572635.stm] , you've got the article, but you've things all around it from link to different articles to headers, footers menus.
All of this affects the search results dramatically so i just want the article itself.
that's the greatest challenge.

Tools for extracting strings from java code for internationalization

For legacy code with lots and lots of strings what method is typically used to extract strings for internationalization?
Am I right in thinking you couldnt simply grep for strings, it could get pretty complitcated, especially with escape characters, escaped quotes etc.,
-SK

When dealing with legacy code, it is nice to have an application that queries you as it extracts the strings. You have a choice whether to accept the string as a localizable entity or not.
There are several tools that do this...including some IDEs like JBuilder. Although it isn't a fully supported or robust tool, Sun has a utility for extracting strings in Java source files:

Function to extract data from a ledger to a detail account

I have created a ledger sheet to collect income and expense chronologically. I have created running totals by account in another sheet using the SUMIFS function, which works well.
I would also like to collect the ledger data in seperate detail accounts so the function would look for an account number field and when it finds a match move the related data to the detail account sheet.
I would like to end up with a Ledger (which I have working) with all entries by date order and a Totals sheet with a running total (which I have working) and a number of separate account sheets with the detail by account. What function do I need to accomplish the detail by account issue?

Attached is a screenshot of what I already have. I would like all the Account 402 entries to appear in order in the Account 402 Escrow sheet.

Air Native Extension for OS X. Cant call functions from native code.

Hi, I am trying to build native extension for OS X.
After creating context, I try to call native function with "call" method, but always I have an error "The extension context does not have a method with the name ..."
In as3 code my ExtensionContext is not null, so it's okay. And in native objective-c code I have a function, which I call in as3 code.
What should I do?
Here my code.
Objective-c:
FREContext AirContext = nil;
    FREObject init(FREContext ctx, void* funcData, uint32_t argc, FREObject argv[])
        return nil;
    FREObject someFunction(FREContext ctx, void* funcData, uint32_t argc, FREObject argv[])
        FREDispatchStatusEventAsync(AirContext ,(uint8_t*) "SOME_EVENT", (uint8_t*) "some information" );
        return nil;
    void ANEContextInitializer(void* extData, const uint8_t* ctxType, FREContext ctx, uint32_t* numFunctionsToTest, const FRENamedFunction** functionsToSet)
        NSLog(@"Entering ContextInitinalizer()");
        *numFunctionsToTest = 5;
        FRENamedFunction* func = (FRENamedFunction*) malloc(sizeof(FRENamedFunction) * *numFunctionsToTest);
        func[0].name = (const uint8_t*) "init";
        func[0].functionData = NULL;
        func[0].function = &init;
        func[1].name = (const uint8_t*) "someFunction";
        func[1].functionData = NULL;
        func[1].function = &someFunction
        // other blank functions
        *functionsToSet = func;
        AirContext = ctx;
        FREDispatchStatusEventAsync(AirContext ,(uint8_t*) "SOME_EVENT", (uint8_t*) "some information" );
    void ContextFinalizer(FREContext ctx) {
        NSLog(@"Entering ContextFinalizer()");
        NSLog(@"Exiting ContextFinalizer()");
    void ANEInitializer(void** extDataToSet, FREContextInitializer* ctxInitializerToSet, FREContextFinalizer* ctxFinalizerToSet )
        NSLog(@"Entering ExtInitializer()");
        *extDataToSet = NULL;
        *ctxInitializerToSet = &ContextInitializer;
        *ctxFinalizerToSet = &ContextFinalizer;
        NSLog(@"Exiting ExtInitializer()");
    void ANEFinalizer(void* extData)
        return;

public class MyANE extends EventDispatcher{
        private static var _instance:MyANE;
        private var extCtx:ExtensionContext;
        public function MyANE()

                if (this.isSupported)
                    extCtx = ExtensionContext.createExtensionContext("my.awesome.ane", null);
                    if (extCtx != null)
                        trace('context is okay'); //this trace works
                        extCtx.addEventListener(StatusEvent.STATUS, onStatus);
                    } else

            </platform>
        </platforms>
    </extension>
And this script Im using for build ANE:
    mv ../as3/bin/MyANE.swc .
    unzip MyANE.swc
    mv library.swf mac/
    rm catalog.xml
    rsync -a ../Obective-C/ANE/Build/Products/Debug/ANE.framework/ mac/ANE.framework/
    adt -package -target ane MyANE.ane extension.xml -swc MyANE.swc -platform MacOS-x86 -C mac .
    mv MyANE.ane ~/Work/_Projects/test/libs-ane/

I haven't done Objective C in a long time, but if I'm not mistaken, it requires the semicolon to terminate a line of code. The line containing "func[1].function = &someFunction" does not have that termination and since that is the function you are trying to execute, maybe that is the source of the error.

Extracting and updating files inside a JAR file... from my code

Hi.
I need some help in the following:
from my code, I need to search a JAR file, open it, unzipped it, then I need to search a xml and property files inside the JAR, after that I need to modify the files and finally, my code has to save the changes and update the JAR file. All that must be from my java code.
How can I do that? I am trying to use Runtime.getRunTime().exec().... but I am not sure that it works. Besides, I don�t know what command to include in the exec() method. Is there any way to do that?
Thanks

The normal reason I see for this requirement is that people want to update a properties or data file. The approach I use it that I first look for the data file in a well defined location and if I find it I use it and update it as required. If I don't fine it I create it base on a template file read from the jar file using getResourceAsSrream().
In this way I never have to update the jar file.

I want to write a ABAP code/ create a Function Modules which extracts data from a DATASOURCE be it any on condition(say date) and the output given should be filtered on some fields
Does a standard datasource be extracted using a custom FM?
Are there any standard FM to do this?

Hi,
go to the TX- SE80 and create the function group.
after take the FM - RSAX_BIW_GET_DATA_SIMPLE
